我已经使用手风琴构建了一个父子系统。结构如下
parent1
child1
child2
child3
parent2
child4
child5
child6
parent3
child7
child8
child9
我还添加了拖放功能。我的要求是我不希望将孩子从当前的父母中拖出。它只能在当前父级中拖动和替换。例如,孩子1,2和3的位置可以与拖动互换,但孩子2不应进入parent2和parent3内。另外,不应该允许parent2子级拖动parent1和parent2
我进行了一项研究,发现手风琴提供了一种财产收容措施:parent,但是它不能正常工作。谁能帮我解决这个问题?

最佳答案
为了实现这些类型的事情,您可以使用jquery可排序的回调。
就您而言,您将需要启动和退出回调
var before_drag;
start: function(event, ui){
before_drag = ui.item.parent().attr('id')
}
out: function(event, ui){
var after_drag = ui.item.parent().attr('id')
if(before_drag != after_drag){
event.preventDefault();
event.stopPropagation();
}
}
